What runs through the vertebral column?

The vertebral column (spine or backbone) is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. The spinal cord runs through its center.

What passes through the vertebral column?

The hollow spinal canal contains the spinal cord, fat, ligaments, and blood vessels. Under each pedicle, a pair of spinal nerves exits the spinal cord and pass through the intervertebral foramen to branch out to your body.

What runs through the hole in the vertebrae?

The spinal cord passes through the foramen of each vertebra. The anterior arch is called the vertebral body.

What is inside the vertebral column?

The spinal cord lies inside the spinal column, which is made up of 33 bones called vertebrae. Five vertebrae are fused together to form the sacrum (part of the pelvis), and four small vertebrae are fused together to form the coccyx (tailbone).

What does the spinal cord go through in the vertebral column?

In humans, the spinal cord begins at the occipital bone, passing through the foramen magnum and entering the spinal canal at the beginning of the cervical vertebrae. The spinal cord extends down to between the first and second lumbar vertebrae, where it ends.

What runs through the spinal cord's central canal?

The central canal (also known as ependymal canal) is the cerebrospinal fluid-filled space that runs through the spinal cord. The central canal lies below and is connected to the ventricular system of the brain, from which it receives cerebrospinal fluid, and shares the same ependymal lining.

What three structures travel through the vertebral foramen?

A number of structures pass through the foramen. These are the root of each spinal nerve, the spinal artery of the segmental artery, communicating veins between the internal and external plexuses, recurrent meningeal (sinu-vertebral) nerves, and transforaminal ligaments.

Does the spinal cord run through the vertebral foramen?

The vertebral foramen houses the spinal cord and its meninges. This large tunnel running up and down inside all of the vertebrae contains the spinal cord and is typically called the spinal canal, not the vertebral foramen.

What does the spinal cord pass through?

The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine. Ligaments and muscles help keep the vertebrae in the right position.

Where is the foramen in the vertebral column?

In a typical vertebra, the vertebral foramen is the foramen (opening) formed by the anterior segment (the body), and the posterior part, the vertebral arch. The vertebral foramen begins at cervical vertebra #1 (atlas) and continues inferior to lumbar vertebra #5.

What are the sections of the spine?

The spine itself has three main segments: the cervical spine, the thoracic spine, and the lumbar spine.

Which part of the brain stem connects with the spinal cord?

The medulla oblongata is the lower half of the brainstem. It controls autonomic functions and connects the higher levels of the brain to the spinal cord.

What are the function of vertebral column?

The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing.

What are the 3 main parts of the spinal cord?

The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions. Three layers of tissue protect the spinal cord: the dura mater, arachnoid mater, and pia mater.

Why do you think the spinal cord runs down the middle of the backbone?

The vertebrae protect the spinal cord, a long, fragile structure contained in the spinal canal, which runs through the center of the spine. Between the vertebrae are disks composed of cartilage, which help cushion the spine and give it some flexibility.

What are the parts of spinal cord?

The spinal cord is divided into four different regions: the cervical, thoracic, lumbar and sacral regions (Figure 3.1). The different cord regions can be visually distinguished from one another.
